C. Gas Connection
• Refer to Section 3 for location of gas line access in
appliance.
• Gas line may be run through knockout(s) provided.
• The gap between supply piping and gas access hole
may be sealed with caulk or aluminum foil tape with a
minimum of 300 ºF continuous exposure rating or stuffed
with non-combustible, unfaced insulation to prevent cold
air infiltration.
• Ensure that gas line does not come in contact with outer
wrap of the appliance. Follow local codes.
• Pipe incoming gas line into valve compartment.
D. High Altitude Installations
NOTICE:
If the heating value of the gas has been reduced,
these rules do not apply. Check with your local gas utility
or authorities having jurisdiction.
When installing above 2000 feet elevation:
• In the USA: Reduce input rate 4% for each 1000 feet
above 2000 feet.
• In CANADA: Input ratings are certified without a
reduction of input rate for elevations up to 4500 feet
(1370 m)above sea level. Please consult provincial and/
or local authorities having jurisdiction for installations at
elevations above 4500 feet (1370 m).
Check with your local gas utility to determine proper
orifice size.
